Collection
of 3087 Raman spectra of minerals,
provided by the RRUFF
project from University of Arizona. (data set from 2012, as part of CrystalSleuth software) For many
mineral species, there are several entries, which allows to get
an impression for the intra- and inter-species spectral variations.
A speed comparison of Spectragryph against their free CrystalSleuth
software, showed Spectragryph to perform 9x faster,
while doing the search with full resolution for all spectra (spectral
similarity algorithm).

Collection
of 5185 Raman spectra from 1677
minerals at four laser wavelengths (data with status: "excellent,
processed, unoriented"), provided by the RRUFF
project from University of Arizona. (most current state, retrieved on 2017-06-13 from http://rruff.info/zipped_data_files/raman/)

Collection
of 2409 UV-VIS-NIR-MIR reflectance/transmittance
spectra of rocks and minerals, meteorites, soil, lunar soil, manmade
materials and vegetation as provided by the
Jet Propulsion Laboratory/JPL (as ASTER
spectral library, version from 2008, all sections). This library
was re-released on 02/02/2018 as "ECOSTRESS
spectral library", with the same content plus some hundred
additional vegetation spectra...
